13 Claims.

This invention relates to improvements in disk harrows of the multiplegang type and more specifically to harrows embodying angs of suchdimensions that the overall width of the implement prohibits convenientstorage or passage through ordinary gateways or entrances to buildings.As commonly practiced, it is necessary at considerable loss of time tolaboriously dismantle portions of the implement before passing throughnarrow passageways, and also for storage.

The objects of my invention are to provide means whereby the implementmay be expeditiously folded to permit passage through the desired gateor building entrance, also to provide means whereby the implement may befolded to either of two different widths, and other objects will behereinafter disclosed in connection with the accompanying drawings inwhich:

Fig. 1 is a plan elevation of a multiple gang disk harrow in transportposition; Fig. 2, a sectional view taken on dotted lines 22 in Fig. 1;Fig. 3, a view showing the implement folded in my preferred manner whenviewed from the front; Fig. 4, a front elevation showing the modifiedmethod of folding the outer gangs; Fig. 5, a sectional view taken ondotted lines 5-5 in Fig. 2, and Fig. 6 is a sectional view taken ondotted lines 86 in Fig. 5.

In said drawings the numeral l indicates the forwardly extending framemembers of a disk harrow embodying a sub-frame it having associatedtherewith a pair of rear disk gang frames l2, the angularity of which isadjustable by levers it, all of common and well known construction. Atthe forward end of frame member ID I fasten converging main framemembers it, side members i and a cross-over member'lfi which is archedat it to clear the sub-frame structure, said members II], M, I5, and I6,constituting the main frame of the implement, and as both sides of theimplement are identical only one will be described in detail. At bothsides of the main frame a triangular shaped main frame extension H ispivotally connected to members l4, 16, as at it and IS, the saidextension having a gang 2D pivotally fastened thereto by a link 25, asat 2!, the inner end of which gang has a bearing 22 formed with an arm23 to which a vertical support 24 is secured for carrying the disk gangframe or carrier 25, as shown in Fig. 2.

Through the arm 23, I pivotally mount a forwardly extending shaft 26which is rotatably mounted preferably in a tube 21 forming a bearingwelded or otherwise fastened to a longitudinally reciprocating pull-bar28, the shaft 26 having stops 29 and 3% to prevent its longitudinalmovement in the tube 217, as in Fig. 5. The said pull-bar extendsforwardly and is supported by suitable guides 3!, 32, Fig. 2, and hasassociated therewith conventional means as lever 33 and quadrant 33'mounted upon the main frame extension for adjusting the gang 20 to thede sired angular position.

During operation of the harrows the gangs are in the angular positionshown by the dotted lines. and ordinarily for transportation the gangsare adjusted by their respective adjusting levers so as to be in thefull line position shown in Fig. 1. When it is necessary to passthrough, for example,

a gateway having a width of twelve feet, with my improved harrow, a pairof supports 34 pivotally fastened, at 35, to the sub-frame H, are raisedto a vertical position, the upper ends thereof being a slight distancebelow the under side of the arched portion l6 of the cross-member IS.The outer gangs are then disconnected from the links 2! after which theouterends of the gangs are raised so as to cause the unit to rotateabout the pivotal connection formed by the shaft 26 and tube 21. Thegangs are rotated until the disk gang frame rests upon the sub-frame ii,causing the outer end of the gang to be towards the center of theimplement. After the two outer gangs have been folded as described, thearched portion E6 of the cross-over frame it will settle upon the upperends of supports 3 5 and thereby sustain the disks sufficiently abovethe ground surface to prevent dragging, when the rear gangs 92 willcarry the entire weight of the implement. If it is necessary to passthrough a gate of less width than twelve feet, the unit is folded asshown in Fig. 4. The main frame extension ll, gang 20 and associatedcontrols are, as a unit, raised to a vertical position by pivoting theextension frame about the points l8 and 19, main-- taining the entireassembly in its vertical position by suitable braces, as at 36. When thegangs are raised to the vertical position as stated, the arched portionIE will rest directly upon the upper surface of sub-frame II, causingthe ends of the cross frame I6 to be on a lower plane than the otherframe members.

In practice I have demonstrated that a harrow embodying my improvementscan be quickly reduced in width to pass through gateways and the like,and as readily adjusted to normal width for field wor 1, at materialsaving in time and labor, and which is capable of reduction to variouswidths in the manner described.
